作者评价了1990年至2001年期间在科比大学医学研究生院口腔颌面外科治疗的13名患者的16个颌骨进行的节段性牙槽骨截骨术的手术区域、适应症和手术程序。截骨术主要适用于正畸治疗的牙齿重新定位有限的病例，社会条件（例如，年龄、时间、经济状况）排除了正畸治疗，或者需要正畸或手术治疗的情况。在上颌前部牙槽骨截骨术的病例中，使用了改良的Wunderer方法，在腭粘膜上做一个切口后，尽可能地磨损粘骨膜瓣，直到腭侧截骨区域可以可视化。上颌后牙段牙槽骨截骨术，由于存在骨块坏死的风险，手术分两期进行。在第一阶段中，在前庭侧进行截骨术，因为前庭牙龈蒂是完整的。在第二阶段，3周后，另一个截骨后腭粘骨膜瓣磨损，以可视化截骨的区域，以及上颌前部节段牙槽骨截骨。
The authors evaluated the surgical area, indications, and procedures for segmental dentoalveolar osteotomy carried out on 16 jaws in 13 patients treated at the Department of Oral and Maxillofacial Surgery, Kobe University Graduate School of Medicine, between 1990 and 2001. Osteotomy was indicated mainly in cases where tooth repositioning by orthodontic treatment was limited, where social conditions (e.g., age, time, finances) precluded orthodontic treatment, or where revision of orthodontic or surgical treatment was required. In cases of maxillary anterior segmental dentoalveolar osteotomy, the modified Wunderer method was used, where after an incision was made in the palatal mucosa, a mucoperiosteal flap was abraded as much as possible until the area of the osteotomy on the palatal side could be visualized. In maxillary posterior segmental dentoalveolar osteotomy, the operation was carried out in 2 stages because of the risk of necrosis of the bone fragments. In the first stage, an osteotomy was carried out on the vestibular side, since the vestibular gingival pedicle was intact. In the second stage, 3 weeks later, another osteotomy was performed after the palatal mucoperiosteal flap was abraded to visualize the area of the osteotomy as well as that of the maxillary anterior segmental dentoalveolar osteotomy.
